Re: Novel plasma phenomenon announced on phys.org

Correctly understood? No. Lamgmuir waves are plasma waves that are near (or equal) to the electron plasma frequency. So these waves propagates in a way (and with a velocity) that depends on the plasma conditions . This paper talks about the formation of "Plasma Structures" (or areas of Structured P...

Re: General anti-fusion attitude

I'll admit that I spend too much time on various forums. Nevertheless, it's led me to observe a common feature of discussions of fusion. A person will come into a thread and proclaim that company so-and-so is a scam, or that fusion is always 10 years away, or that fusion won't be realized for anoth...

Re: EM Drive

Indeed I agree. But from what they said, they are using their own money and do not have any external investors/grant, so they probably need to balance their economic possibility with their wishes. The good point is that they got lot of publicity in the last few months, so maybe someone else will ste...

Re: EM Drive

It seems like Barry-1 experienced a failure on the power bus and they lost communication with it, apparently before they could turn on the test engines. I have no idea of what their collaboration agreement was, but having an experiment in standby for so long in a cubesat is generally not a smart thi...

Re: Avalanche Energy

Their idea is indeed innovative, I agree that they need to publish real data before being considered a real contender, way too many times we saw simulations twisted by unrealistic starting hypothesis. As for their the parameter space, it is strictly connected to the feedthrough value that they can r...

Re: EM Drive

What you say matches the Norad data but not the Barry website. At least at first blush… What I meant is that Barry-1 orbital behavior is normal of any satellite in the same orbit as it is. The satellite will slowly circularize its orbit and than enter a low inward spiral trajectory toward earth. So...

Re: EM Drive

Scratching my head - the Barry data shows t he e satellite altitude falling and velocity increasing, until recently, when velocity seems to have peaked gracefully and altitude similarly bottomed. The norad data linked earlier shows the SMA continuing to decline, along with the eccentricity. Not und...

Re: EM Drive

Today's tweet from IVO Ltd's CEO: LEOP of Barry-1 is going very slowly, but it is progressing. I appreciate @RogueSpaceCorp's work toward preparations for the Quantum Drive's first test. No exact date yet. Launch and Early Orbit Phase should not last 2 months for a cubesat. I hope they do not have ...

Re: Humble hopes for 2024

5. The USA doesn't go crazy during its election year. As a non US citizen following US politics from abroad I had the feeling that USA already lost any rationale in the coming elections..... Very humble hope: 4. IVO's Quantum Drive demonstrably works. Same here, very little hopes but what a feat wo...

Re: Thea Energy

Their idea was to use planar HTS coils and use control electronics to shape the magnetic field, hence removing the complexity of manufacturing Stellarators.

Nice to see that they are moving forward with the plan.

Re: MIFTI - Magneto Inertial Fusion Technology Inc

MIFTI has not been releasing any news or papers since their DARPA-E grant which ended in 2019 and didn't bring any meaningful experimental result. Today they are hardly leader in anything related to Inertial Fusion except for wishful thinking. US Nuclear Corp is a company with only 2 million in reve...

Or perhabs an hitherto unknown instability?
Possible as that tends to be the major showstopper for every fusion candidate we had in the last 40 years.....

Re: Happy Holidays everyone!

Merry Christmas everyone.

My desire under the tree was to get a working fusion machine by the end of 2024.
I hope that Santa will consider me to have been a good boy in 2023 and grant my wish! :mrgreen:

Re: EM Drive

If we consider only air drag, than at 500 Km height the air density can oscillate up to 2 orders of magnitude, from a minimum of 10^-13 to a maximum of 10^-11 Kg/m3 due to the sun flux oscillations and sun/earth geomagnetic activity that compress and expand the air bubble around the planet. If we as...
